The New Jersey Department of Environmental Protection (DEP) has adopted groundbreaking changes to the state’s stormwater management rules. The new amendments emphasize engineering with nature and require permit applicants to use green infrastructure, rather than more traditional engineered structures, to reduce stormwater runoff and achieve water quality goals. The new rules will help the state manage polluted runoff, reduce flooding, and improve its resilience to storms and impacts from climate change.
The DEP’s work on the amendments has spanned years of research and cooperation with other state agencies and stakeholders. The amendments will take effect in one year, allowing time for a smooth transition to the new requirements, flexibility for major developments that are currently in the design and planning process, and time for municipalities to develop accompanying local ordinances and for training for engineers and review staff.
